The thickness of the 16b sprocket is 17.02mm. According to GB/T1243, the minimum inner section width b1 of the 16A and 16B chains is: 15.75mm and 17.02mm respectively. Since the pitch p of these two chains is both 25.4mm, according to the requirements of the national standard, for the sprocket with a pitch greater than 12.7mm, the tooth width bf=0.95b1 is calculated as: 14.96mm and 16.17mm respectively. If it is a single-row sprocket, the thickness of the sprocket (full tooth width) is the tooth width bf. If it is a double-row or three-row sprocket, there is another calculation formula.
